Andrew Shaw's goal 1:47 into overtime gave the Chicago Blackhawks a 4-3 victory against the Washington Capitals in a meeting between two teams that will see each other again Tuesday night -- for real.

Defenseman Nick Leddy scored twice and assisted on a goal by Jimmy Hayes as the Blackhawks took three one-goal leads, only to see the Alex Ovechkin-less Capitals pull even each time. Mikhail Grabovski and Marcus Johansson scored in the second period for Washington and Joel Ward forced overtime when he beat Nikolai Khabibulin with 5:01 remaining in regulation.

The Blackhawks have been trying to get Leddy to shoot more. Saturday's performance might help the coaching staff get through to the 22-year-old.

"Just shooting the puck always creates offense; whether it goes in or it creates a chance for someone else," Leddy said.

Washington, which ended the preseason with a 4-0-4 record, didn't have Ovechkin; he was in Greece carrying the Olympic torch. But he'll be back with the Capitals on Sunday and will be wearing his familiar No. 8 when they take the ice at the United Center on Tuesday night (8 p.m. ET; NBCSN).

"Even when they played us at home, they're a fast team. They're a very good team. They're Stanley Cup champs," Washington coach Adam Oates said. "They're a very good hockey team. We respect them. We didn't play our best tonight and we still got the overtime, so there has to be some silver lining in there."

Other than having trouble holding leads, the Blackhawks looked like a team ready to defend its Stanley Cup; they outshot Washington 37-15 and went 38-24 (61 percent) in the faceoff circle as they finished the preseason with a 4-0-2 record.
